General
Colour	Blue

The shrink tube Pliofine B-EX 3800 (1.22m) blue from Ses-Sterling is a professional protective material for cables, wiring, and electrical connections. It provides mechanical and electrical insulation as well as protection against environmental influences such as moisture, dust, or mechanical stress. The shrink tube is activated by heat (e.g., with a hot air blower) and shrinks to approximately half its original outer diameter — a ratio of 2:1, referred to in technical terms as the shrink ratio. The blue color identifies the tube and serves for visual differentiation in complex installations.

Applications

The shrink tube is suitable for use in electrical and IT installations as well as in industrial electronics. It is frequently used for connecting cables, shielding connections, or marking wiring. The application is suitable for indoor and outdoor environments, where specific environmental conditions such as temperature, humidity, or chemical influences determine the selection of the appropriate shrink tube type. The blue-colored version is particularly suitable for applications requiring clear visual identification.

Functions and Features in Detail

The Pliofine B-EX 3800 shrink tube is characterized by high mechanical strength and good heat resistance. It shrinks evenly when heated, forming a tight, shape-stable sleeve around the contained cables or wires. The blue color enables easy visual differentiation, especially in complex systems with multiple wires. The length of 1.22 meters provides sufficient material for multiple applications, and the exact length can be cut to requirement. The packaging contains a single piece.

Technology Explained Simply

The shrink tube is made of a thermoplastic material that changes shape when heated. At a temperature of approximately 100 °C to 120 °C, the tube begins to shrink and tightly conforms to the cables inside. The shrink ratio of 2:1 means the tube shrinks to approximately half its original diameter. This ensures a tight fit and reliable protection. Shrinking is achieved by heat, generated using a hot air blower or similar device. The blue surface remains after shrinking and serves as a visual identifier.

Compatibility and Accessories

The shrink tube is suitable for use with cables and wires of various diameters, with the 2:1 shrink ratio enabling flexible adaptation. It can be combined with other shrink tube types to meet different protection requirements. The use of a hot air blower or other heat sources is required to activate the shrinking process.

Installation and Mounting

Installation is performed by sliding the shrink tube over the area to be protected, followed by heating with a hot air blower. Care should be taken to ensure even heat distribution to avoid uneven shrinking or damage to the tube. The temperature should not exceed 120 °C to prevent overloading the material. After shrinking, the tube forms a tight, shape-stable sleeve that protects the enclosed wires. The length of 1.22 meters allows multiple applications from a single piece.

Operational Advantages

The shrink tube provides reliable mechanical and electrical insulation. The tight fit after shrinking prevents moisture, dust, or other environmental influences from entering. The blue color facilitates visual identification in complex installations. The simple handling and quick installation make the shrink tube a practical tool for electrical and IT installers. Its use is universal and adapts to various requirements without requiring additional tools or materials.
